Description
Technical field
The present invention relates to mobile communication technology field, the indicating means, the Apparatus and system that switch in particular to a kind of multiband minizone.
Background technology
Cell reselection and switching are the important functions of cell mobile communication systems.In order to realize smoothly cell reselection, UE need to measure the signal quality of different districts, so that it is resident to select suitable community to carry out.UE, after certain community and network connect, still needs the signal quality of its neighbor cell to measure, to select suitable community to switch, thereby meets mobility requirement.
Fig. 1 is under connected state, and in Long Term Evolution (Long Term Evolution, referred to as LTE) system, terminal is carried out the signaling process figure measuring.As shown in Figure 1, measurement control message is sent to UE by network side, and wherein, this measurement control message comprises other association attributeses of measuring mark, measuring object, report configuration and measuring.Wherein, configured carrier frequency and Neighboring Cell List etc. in measuring object, indicating terminal is measured the carrier frequency Shang community configuring in measuring object; In report configuration, be provided with that Event triggered reports or periodic report, trigger event defines (A1, A2, A3 by trigger condition ...).Terminal (UE) receives to be measured after control message, goes to carry out measurement according to the measuring object of measuring in control message, and reports network side according to measurement result and report configuration integrate measurement report.
In addition, the ability information that base station can inquiry terminal, terminal by the capability reporting of self to base station, the band information that the packets of information reporting is supported containing terminal.Fig. 2 is the ability information signaling process schematic diagram of base station inquiry terminal, and as shown in Figure 2, base station is by UECapabilityEnquiry message request UE reporting ability, UE by UECapabilityInformation message by the capability reporting of self to base station.
The central task carrier frequency of current area is by EARFCN(E-UTRA Absolute Radio Frequency ChannelNumber) identify, the work physical frequencies that the EARFCN of community has comprised community and the information of working band, below with the EARFCN(physical frequencies of working, working band) identify the working carrier frequency of this community.
A frequency band is only supported in current area, but because operator introduces new frequency band, has coincidence, thereby draw a kind of new scene in frequency with the frequency band having existed, and multiband is supported in community, as shown in Figure 3.When terminal is switched in multiband minizone, may cause following problem: terminal is switched to behind Target cell, get back to again cell-of-origin.For example, current You Liangge community, community 1, work physics frequency f 1, supports that frequency band x(is below with community 1(f1, x) form describe), community 2(f2, y, z).In the system message broadcast of community 1, the packets of information of community, adjacent area 2 is containing the EARFCN(f2 of community 2, y) and the frequency band z that supports of community 2, the frequency band z wherein supporting, by newly-increased expanded signalling indication, supports the terminal of corresponding signaling version could correctly parse newly-increased expanded signalling.In the system message broadcast of community 2, comprised frequency band x and y that community 2 is supported, wherein y describes in the signaling of expansion.Terminal enters connected state in community 1, because terminal is not supported frequency band y, task is measured to terminal configuration in base station, measuring object is the carrier frequency EARFCN(f2 of community 2, z), base station is according to measurement report, allow terminal be switched to community 2(f2, z), then because the business of terminal discharges, need to enter IDLE state, but terminal is not supported frequency band y, and terminal is the terminal of legacy version, cannot resolve newly-increased expanded signalling, be that terminal can only be seen community 2(f2, y), therefore terminal cannot be resident to community 2, terminal can only select other communities such as community 1 is carried out resident, or enter without community resident state.For the problems referred to above, effective solution is not also proposed at present.
